(Granted under the act of March 3, 1883, as amended April 30, 1928; 3700. G. 757) 3 Claims.

This invention relates to a clamp for attaching a horizontal beam to avertical post.

An object of this invention is to provide a clamp that will secure ahorizontal beam to a vertical post and will permit rapid detachment.

Further objects and advantages of this invention, as well as itsconstruction, arrangement and operation, will be apparent from thefollowing description and claims in connection with the accompanyingdrawings, in which Fig. 1 is a front elevation of the fastener;

Fig. 2 is a front elevation of the bracket; and

Fig. 3 is an isometric view showing the arm of the clamp in use.

A preferred embodiment of the invention is illustrated in Figs. 1, 2 and3 wherein the arm of the clamp is designated generally by referencecharacter H3. Arm Iii is made of strip metal and is bent to provide ahorizontal member ll. Depending from one end of horizontal member II isa vertical member l2 and depending from the other end of horizontalmember II is a vertical member l3. Connected to the lower extremity ofvertical member i3 is a horizontal offset member l4 from the outer endof which depends a third vertical member l5, which terminates in a loopHi, the end of the loop l6 being welded to the vertical member I5.

The arm Ii! is pivoted to a bracket 20 that is fastened to the post 42by means of screws (not shown) that pass through apertures 22 in a plateor vertical member 2|. Vertical member 2| has outwardly extendingflanges 23 that have upper and lower bolt-holes 2424.

A bolt 30 passes through the lower of the boltholes 24 and through theloop IE to provide a pivotal attachment of the arm I to the bracket Zil,a nut (not shown) on the end of bolt 30 bein utilized to attach the armIt) to the bracket 2|].

Vertical member l of arm ID is confined between vertical member 2| ofbracket 20 and a lock bolt 32 that passes through the upper bolthole 24.

A chain 33 can be attached to lock bolt 32 as by welding and fastened topost 42 by a staple 34 to prevent misplacement of the lock bolt 32.

In the operation of the device, beam 40 is placed in the notch 4| of thepost 42 and the arm I0 is pivoted about the bolt 30 so that offsetportion l4 rests on the top 43 of post 42 and the members ll, [2 and I3encompass beam 40, said members having suiflcient resilience to beforced over beam 40 and to resume the shape illustrated. Lock bolt 32 isthen inserted through upper bolthole 24 to hold the arm rigidly inplace.

Various modifications and changes can be made in the subject devicewithout departing from the scope of the invention.

The invention described herein may be manufactured and used by or forthe Government of the United States of America for governmental purposeswithout the payment of any royalties thereon or therefor.

I claim:

1. A clamp for attaching a horizontal beam to a vertical post notched atits upper end, the beam being disposed in the notch, comprising a striphaving an elongated horizontal member, two vertical members rigidlysecured to and depending from opposite ends of said horizontal member, asecond horizontal member offset from the lower end of one of saidvertical members, a third vertical member depending from the outerextremity of said offset member, said third vertical member terminatingin a loop at its lower end, a bracket for attachment to the side of thepost, said bracket having a vertical member, parallel flanges projectingfrom the edges of said vertical member, said flanges having upper andlower bolt-holes, a bolt passing through the lower of said bolt-holesand through said loop, a nut on said bolt, a second bolt passing throughthe upper of said bolt-holes, said third vertical member being disposedbetween said flanges and also between said vertical member of saidbracket and said second bolt.

2. A clamp for securing a beam on a post comprising a metal strip, legmembers secured rigidly to and depending from opposite ends of saidstrip, an ofiset member secured rigidly to and depending from the end ofone of said leg members parallel to said strip, a foot member securedrigidly to and depending from the end of said oiiset member andterminating in a loop at its end, a bracket adapted to be attached tosuch post, said bracket comprising a plate having parallel flangesprojecting therefrom, a first bolt passing through first bolt-holes insaid flanges and said loop to carry said foot member rotatably, and asecond bolt secured removably in second bolt-holes in said flanges tosecure said foot member against said plate.

3. A clamp for securing a beam on a post comprising a metal strip bentto define a generally U-shaped member having one leg including an offsetportion and a foot depending from the end of said oflset portion andterminating in a loop, a bracket adapted to be attached to such post,said bracket comprising a plate having parallel flanges projectingtherefrom, a first bolt passing through first bolt-holes in said flangesand said loop to carry said strip rotatably, and a second bolt securedremovably in second b01t-h01es in said flanges to secure said footagainst said plate.
